The change of the resistance of single crystals of pure gallium (which had the pseudo-tetragonal axis parallel to the length of the wire) in a magnetic field perpendicular to the wire has been measured at liquid helium temperatures. 1. At 4.22ยฐK the increase of the resistance is larger than at liqu
A discussion is given of the considerations of Meixner and Koh-1 e r according to which the change of resistance in a magnetic field is not necessarily an even function of the field strength: it may contain odd powers of H andeven a linear term. No experimental evidence for the existence of such ter
## Synopsis It is supposed that the coercive force of an iron film can be evaluated by the value of the field at an extreme in the curve of the change of the electrical resistance as a function of the magnetic field. For the bulk material this supposition is approximately right at room temperature
