Quadrupole Excitations in Magnetic Susceptibility of Magnetic Nanoparticle Fe8
Magnetic susceptibility dependence on temperatures in different magnetic fields will be discussed. Until today, to calculate magnetization and magnetic susceptibility, only dipole excitations have been considered, but, due to the symmetry of operators in Hamiltonian and also to achieve more accuracy...
