Magnetization switching in nanoscale devices induced by electric currents has been a subject of intensive research in recent years.1 One of the most studied approaches is the transfer of spin angular momentum between non-collinear ferromagnetic layers, an e ect known as spin transfer torque (STT).2,3 In this case, the charge cur-

Interplay of Strongly Anisotropic Metal Ions in Magnetic

Nov 23, 2016 The key characteristic of single-molecule magnets (SMMs) is the anisotropy-induced blocking barrier, which should be as efficient as possible, i.e., to be able to provide long magnetic relaxation times at elevated temperatures. The strategy for the design of efficient SMMs on the basis of transition-metal complexes such as Mn12Ac is well established, which is not the case of complexes ...

It was predicted by Slonczewski1 and Berger2 that magnetization of a nanomagnet may be flipped by a spin polarized current through the so-called “spin-torque” effect and this was later demonstrated experimentally.3,4 However, the early spin-torque systems were metal based that allowed only a small change in the magnetoresistance.
