a continuous wave (cw) He±Cd laser (325 nm) with an output power of 20 mW was used as the excitation source. The PL was dispersed through a SPEX Triax 500 spectrometer with a 600 lines/mm grating and was detected by a nitrogen-cooled charge-coupled device (CCD) camera. The development of surfaces that have switchable properties offers a new dimension in the(More)
Large heat currents are obtained in Co/Cu/Co spin valves positioned at the middle of Cu nanowires. The second harmonic voltage response to an applied current is used to investigate the effect of the heat current on the switching of the spin valves. Both the switching field and the magnitude of the voltage response are found to be dependent on the heat(More)
