12 Feb 2019 | | Abstract: | Proximity-induced magnetization (PIM) has broad implications across
interface-driven spintronics applications employing spin-currents. We directly
determine the scaling between PIM in Pt and the temperature-dependent interface
magnetization in an adjacent ferromagnet (FM) using depth-resolved
magnetometry. %PIM does not follow the expected linear scaling with the FM
interface magnetization due to the Pauli susceptibility. Instead, PIM vanishes
whilst the FM interface magnetization remains. The magnetization due to PIM
does not follow the generally expected linear scaling with the FM interface
magnetization, as a function of temperature. Instead, it vanishes whilst the FM
interface magnetization remains. The effective magnetic susceptibilities of
heavy metal (HM) layers are shown to give rise to the previously unexplained
asymmetric PIM found in HM/FM/HM trilayers. | | Source: | arXiv, 1902.4308 | | Services: | Forum | Review | PDF | Favorites | |
