Switching magnetic domains in magnetic memories requires normally magnetic fields which are generated by electrical currents, hence requiring large amounts of electrical power.
In general, ferromagnets are divided into magnetic domains and separated by surfaces known as Bloch walls.
Using spin SEM in this way to observe the magnetic domains on the Co (0001) surface at various temperatures helps in investigating the magnetic properties associated with reported phase transitions.
The bias magnet provides a magnetic field to orient the magnetic domains along the y-axis direction.
The nonmagnetic layer can then influence the magnetic one, with electric fields in the nonmagnetic layer pushing around the magnetic domains in the magnetic layer.
Each of these magnetic domains is made of a large collection of magnetised atoms, whose magnetic polarity is set by the hard disk's read/write head to represent data as either a binary one or zero.
Figure 3S, https://www.raccefyn.co/index.php/raccefyn/ article/downloadSuppFile/422/1992, shows how for all samples, the magnetic moment (M) was low at 50K and grew slightly to 100K, then at approximately 120K it increased drastically until it reached its maximum value due to the magnetic domains alignment relative to the external field.
The net result can be a reduction in the magnon-drag thermopower at high magnetic fields and when all magnetic domains are aligned in the direction of the applied magnetic field.
The magnetic properties of GBs in sintered Nd-Fe-B permanent magnets play a crucial role for the nucleation of reversed magnetic domains as shown in our previous publications [21,22].
Particles bigger than 120 nm present several magnetic domains with a lower net magnetization.
The motion of magnetic domains can be divided into reversible or irreversible movement and rotation.
