The term Gilbert damping represents the rate at which magnetization relaxes towards its equilibrium position. In magnetization dynamics it is usually modeled using a phenomenological term in the Landau-Lifschitz-Gilbert equation, with direction proportional to the vector product of the magnetization and its time derivative. Magnitude of the Gilbert damping torque is proportional to a dimensionless parameter known as Gilbert damping.

In our group we focus on the origin of the Gilbert damping, which can be studied using ab initio calculations.

Magnetism is a class of physical phenomena that are mediated by magnetic fields (Wikipedia).

A large part of the research in our group is focused on study of magnetic materials, especially ferromagnets and antiferromagnetis. Both types of materials are important for spintronics since some of them can be used for generation of spin currents and/or their magnetic moment can be manipulated by spin currents.

Spin waves are propagating disturbances in the ordering of magnetic materials. These low-lying collective excitations occur in magnetic lattices with continuous symmetry. From the equivalent quasiparticle point of view, spin waves are known as magnons, which are boson modes of the spin lattice (Wikipedia).

In our group we study spin waves and their potential utilization in spintronics. Using analytical and numerical methods we study, how spin waves can be generated by means of spin current, laser pulses, and domain wall dynamics.

Spintronics, also known as spin electronics, is the scope of physics which study the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. In the last decades, spintronics is one of the most developing area in solid state physics connecting physics with material science and engineering.
