In memory nanodevices based on phase changes induced thermally, the process of information recording is a reversible transition between the structurally ordered (crystalline) and disordered (amorph...

Current magnetic memories are based on writing and reading out the domains with opposite orientation of the magnetization vector. Alternatively, information can be encoded in regions with a different value of the saturation magnetization. The latter

The relaxation rate for phase transformations depends on how the system is far from its thermodynamic equilibrium. If, for example, temperature in the system approaches to the phase transition point, the relaxation rate becomes close to zero. We theo

Manipulation of magnetism using laser light is considered as a key to the advancement of data storage technologies. Until now, most approaches seek to optically switch the direction of magnetization rather than to reversibly manipulate the ferromagne

It is well established that electrical methods, such as the application of a high-density (10(10)-10(11) A m(-2)) current, can be employed for the switching of magnetization in thin ferromagnetic films and hetero-structures after their patterning at

We study the magnetocaloric effect in layered systems composed of a ferromagnet with a relatively low Curie temperature (TC), which is sandwiched by stronger ferromagnets and exchange coupled to them across the interfaces. Switching of magnetization

It is of interest to explore magnetic configurations and phase transitions at the interfaces between different magnetic materials by employing nondestructive and element-specific methods such as resonant X-ray magnetic reflectometry (RXMR). Using RXM

We explore whether it is possible to enhance the magnetocaloric effect (MCE) in layered systems, where a refrigerant (weak ferromagnet) is sandwiched by strong ferromagnets, by magnetizing the spacer with the effective field that results from its exc

In magnetic data storage, information can be corrupted by external magnetic fields or thermal fluctuations. A possible solution to both problems is reversibly altering the $m\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}g\phantom{\rule{0}{0ex}}n\pha
