ScholarBank@NUS Repository. https://doi.org/10.1063/1.3463474 | Abstract: | We use lateral superconductor (SC)-ferromagnet (FM)-SC device to probe the magnetization reversal process of micron sized FM disk. Upon decreasing external magnetic field from saturated state, a buckling pattern forms first. The onset of buckling pattern and its switching to vortex state are studied with the help of Andreev conductance of the SC-FM interface below the critical temperature (Tc) of SC and the magnetoresistances both below and above the T c. In the latter case, micromagnetic modeling has been carried out to interpret the experimental results by taking into account the current distributions when the electrodes are at different states. © 2010 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/82930 | ISSN: | 00036951 | DOI: | 10.1063/1.3463474 |
