Investigation of the tunnel magnetoresistance in junctions with a strontium stannate barrier
Matthias Althammer, Amit Vikam Singh, Sahar Keshavarz +5
We experimentally investigate the structural, magnetic and electrical transport properties of LaSrMnO based magnetic tunnel junctions with a SrSnO barri…
Cross-spectrum Analyzer for Low Frequency Noise Analysis
Xing Zhong, Sahar Keshavarz, Josh Jones +2
The design and performance of a sensitive and reliable cross-correlation spectrum analyzer for studying low frequency transport noise is described in detail. The design makes use o…
High Temperature Ferromagnetism in Zn1-xMnxO semiconductor thin films
Nikoleta Theodoropoulou, Vinith Misra, John Philip +5
Clear evidence of ferromagnetic behavior at temperatures >400 K as well as spin polarization of the charge carriers have been observed in ZnMnO thin films grown on Al2O3 and MgO su…
Large magnetoresistance using hybrid spin filter devices
P. LeClair, J. K. Ha, H. J. M. Swagten +3
A magnetic "spin filter" tunnel barrier, sandwiched between a non-magnetic metal and a magnetic metal, is used to create a new magnetoresistive tunnel device, somewhat analogous to…
Observation of band structure and density of states effects in Co-based magnetic tunnel junctions
P. LeClair, J. T. Kohlhepp, C. H. van de Vin +7
Utilizing Co/AlO/Co magnetic tunnel junctions (MTJs) with Co electrodes of different crystalline phases, a clear relationship between electrode structure and junction trans…
