A team of researchers has proposed a new concept for magnet-based memory devices, which might revolutionize information storage devices owing to their potential for large-scale integration, non-volatility, and high durability. Details of their findings were published in the journal Nature Communications on March 7, 2024. Spintronic devices, represented by magnetic random access memory (MRAM), utilize the magnetization direction of ferromagnetic materials to memorize information. Because of their non-volatility and low energy consumption, spintronic devices will likely play a pivotal role in future information storage components.

If a magnet keeps doing work, will its magnetism be weakened or even disappear?

If a magnet keeps doing work, will its magnetism be weakened or even disappear? There are many misconceptions about magnets and how they are magnetic. Since the magnetism of a magnet is invisible and intangible, it will be more abstract in the eyes of many people, and it is difficult to reflect it intuitively. First of all, whether a magnet does work or not is not directly related to its own…

FEA for Permanent Magnetic Circuit Simulations

FEA for Permanent Magnetic Circuit Simulations When we discuss simulating a magnetic circuit, you’ll often hear the acronym FEA. This stands for Finite Element Analysis. It’s a common simulation method in many software packages for electro-magnetic fields, heat, and stress. It boils down to breaking a 2D or 3D representation of the environment into a series of nodes (or points) at which the…

Ship Bingo: Zoro + Perona

ship bingo! // accepting!

I don't feel like I love a lot of One Piece ships, but Zoro and Perona is way up there on the list of ones I do really like! I think they're so much fun and enjoy their bickering banter a lot - and I think Perona was really sad to see him go after the time skip. Overall I think it's a super cute ship and has a lot of potential! Probably falls somewhere in my top 5 ships if I ever sit down to figure those out. Thanks for asking!

Ferromagnetic Core Memory

64x64 bit ferrite ring (core memory) memory that can store 4096 bits of information. In the 50's and 60's, computers the size of a room had such memories. They were usually handmade.

The picture above shows the memory used in the Russian Saratov-2 (PDP-8 copy) computer. Check these out too if you are interested in retro computing

I always said I was afraid of MRIs because I’m afraid I’ll have some kind of metal in me that I’ve forgotten about and I literally do. I didn’t remember until this moment that I’ve got a permanent retainer.

#Apparently that’s fine it’s not ferromagnetic #But see. I literally did forget.

Ferromagnetic materials display the alignment of electron spins within small areas called domains in the absence of a magnetic field.

Room-temperature long-range ferromagnetic order realized in a confined molecular monolayer

How can we manipulate intermolecular exchange interaction to achieve long-range spin ordering? The answer to this question is of great importance in understanding and modulating magnetic behavior at the microscopic scale and in developing new macroscopic magnetic materials and devices. However, temperature and environment play a decisive role in molecular magnetic behavior and spin ordering. At high temperatures, thermal uplift disrupts the spin ordering and disables intermolecular exchange interactions. According to the Mermin-Wagner theory prediction, there is no long-range spontaneous magnetic ordering in two-dimensional systems. Therefore, realizing two-dimensional room-temperature ferromagnetic molecular materials still remains to be a challenge in this field. If solved, it will be vital not only for a fundamental understanding of the nature of magnetism but also for opening new avenues towards a new magnetic material platform.

Elemental Iron (Fe) - Fundamental Magnetic Element

Elemental Iron (Fe) – Fundamental Magnetic Element

Elemental Iron (Fe) – Fundamental Magnetic Element The basis of all magnetic science started with iron. It is present in most permanent and soft magnetic materials that MPCO Magnetics designs and manufactures. It is abundant in nature, the 4th most common element by number and 1st most common by mass; making it relatively inexpensive. Humans have thousands of years of experience working with…

Of particular interest is a material that converts to a magnet when dehydrated, despite there being no associated change to the framework structure (see figure 7.56).

Ship Bingo: Law + Monet!

ship bingo! // accepting!

Y'know, strangely, this is just one of those ships that I have like... no thoughts on at all? I guess it just didn't occur to me to see it as one or register that it was even a thing. Like I know Monet made the one "oh? is it a date?" flirty comment and I may attribute this to my irl inability to notice people flirting but I just literally never thought about this during my speed read-through last year. I'll be curious to see if I interpret anything differently when I make my way back up to PH this time around! So like I'm not even going to say neutral for now so much as "obliviously unaware that this is a thing that could even remotely happen" - no stance yet.

#ferromagnetic #♡ // ooc ;#♡ // answered asks ;#to be revisited at a later date! this was a fun ask though - thanks for sending it!#i usually have many thoughts on ships whether good or bad so this one amuses me in that I have nothing.
