Recently, the-semiconductor ZnO, normally n-type, doped with magnetic impurities was reported to be ferromagnetic above room temperature. Since ZnO is optically transparent, ferromagnetic Zno should a transparent magnet as well. The purpose of this s

We studied the structural and magnetic properties of Ti1−xCoxO2 powder samples synthesized by the sol–gel method. In order to study the post annealing effect on the magnetic properties, the same precursor was annealed at 770 K for 5 h in air and

The peak of the spin glass relaxation rate, S(t)=d{-M_{TRM}(t,t_w)}/H/{d ln t}, is directly related to the typical value of the free energy barrier which can be explored over experimental time scales. A change in magnetic field H generates an energy
