Magnetoelectric (ME) effects in composite ferromagnet-piezoelectric (FM/PE) heterostructures realize the mutual transformation of alternating magnetic and electric fields, and are used to create magnetic field sensors, actuators, inductors, gyrators,

We report a non-clinical, mathematical method of studying genetic sequences based on the information theory. Our method involves calculating the information entropy spectrum of genomes by splitting them into “windows” containing a fixed number of

The information capacity of the universe has been a topic of great debate since 1970s, and continues to stimulate multiple branches of physics research. Here we used Shannon's information theory to estimate the amount of encoded information in all th

The multicaloric effect is defined as the adiabatic reversible temperature change in multiferroic materials induced by the application of an external electric or magnetic field, and it was first theoretically proposed in 2012. The multicaloric effect

We describe theoretically and experimentally a previously unobserved mechanism for the induction of the nonlinear magnetoelectric response in ferromagnet-piezoelectric multiferroic composites. We show that contributions to the nonlinear magnetoelectr

Ferroelectric random access memory (FRAM) is a two-state non-volatile memory, in which information is digitally encoded using switchable remanent polarization states within a ferroelectric thin film capacitor. Here, we propose a novel non-volatile me
