Abstract
The resistance of metallic point contacts has been measured in magnetic fields up to 20 T. The observed monotonously increasing component in the magnetoresistance has its origin in the resistivity-dependent part of the contact resistance (the ‘‘Maxwell’’ resistance). In the case of compensated metals, it is simply a manifestation of the (strongly anisotropic) bulk magnetoresistance. In the case of uncompensated metals, this (quadratic) component is caused by the Corbino effect.Keywords
