Yes, note parkhomov seam to indicate that the form of the applied ac is important. Hence if you take that at face value the conclusion is that induced varying magnetic field is important. Why couple that with the heating. Much better to decouple and search for optimal stimulation in the test at each level of heat. Den 17 apr 2015 00:11 skrev "Bob Higgins" <[email protected]>:
