The mean‐square pressure distributions in the ultrasonic fields generated in water by quartz transducers of various shapes were presented on an oscilloscope screen and photographed. The beams, pulsed at an audiofrequency, were swept back and forth

Owing to their high internal fields, antiferromagnetic materials have natural resonant frequencies in the millimeter and submillimeter wavelength region of the electromagnetic spectrum. Since these normal modes are circularly polarized and can be tun

The reflection coefficient for plane waves incident obliquely on a medium in which the velocity decreases exponentially is computed approximately using the WKB method and compared with a computation from the rigorous solution. The approximate reflect

The temperature dependence of the effective internal fields of NiO has been determined from antiferromagnetic resonance experiments at submillimeter frequencies using Fourier transform spectroscopy and at millimeter wavelengths with the usual spectro

The effective internal field (2H E H A )1/2 as well as its temperature dependence has been found from anti-ferromagnetic resonance experiments for two different single crystals of MnTiO3, and from absorption edge data for a pure powder sample. The da
