An investigation of electrical, magnetic, and microwave properties is presented for Nd1-xSrxMnO3-y (NSMO) thin films. The NSMO thin films were deposited on (100)-oriented LaAlO3 substrates using both high-pressure sputtering and laser-ablation methods. Several films with different doping concentration ranging from 0.17 to 0.33 were tested for microwave loss and their frequency dependence on the dc magnetic field. The films exhibited Curie temperatures ranging from 220 to 60 K, and saturation magnetization from 0.3 to 0.1 T. The feasibility of applications of magnetic perovskites for magnetic tuning of resonators is analyzed and discussed. (C) 2002 American Institute of Physics.
