DOI: 10.1002/aelm.202000976
Abstract: One of the critical issues in spintronics‐based technologies is to increase the data storage density. Current strategy is based on shrinking the devices size down to tens of nanometers, or several nanometers, which is reaching… read more here.

DOI: 10.1063/1.5058265
Abstract: Barrier interface condition is critical for spin-polarized tunneling and spin-transfer torque switching in CoFeB∣MgO∣CoFeB-based magnetic tunnel junctions. The differential tunnel conductance gV contains information on CoFeB’s magnetic properties at tunnel interfaces. Experimentally, we find gV… read more here.

DOI: 10.1088/2053-1591/ab332b
Abstract: The temperature dependences of spin/orbital magnetization switching behaviour were measured for CoFeB/MgO and CoFeB/Ta multi-layered films. The magnetization switching behaviours were different between the spin specific magnetic hysteresis (SSMH) curve and the orbital specific magnetic… read more here.

DOI: 10.1109/tmag.2017.2707081
Abstract: Spin–torque ferromagnetic resonance (ST-FMR) spectra of nano-scaled CoFeB/MgO/CoFeB full perpendicular magnetic tunnel junctions (p-MTJs) were investigated, especially in detail at low dc-bias voltage region. Usually in in-plane magnetized MTJs (i-MTJs), the ST-FMR spectrum line shape… read more here.
