The notion of this convention grew out of the swiftly increas­ ing quantity of experimental proof. and theoretical innovations on the topic of the matter of crystal-field results in metals and alloys. The crystal box performs a massive function within the figuring out of the lively point constitution of ions in condensed subject. In partic­ ular, the magnetic homes of infrequent earth metals and alloys are strongly encouraged by way of the crystal box. within the phenomenological conception the crystal box effectively describes the static and dynamic magnetic houses of those platforms. however the microscopic starting place of the crystal box in metals isn't but totally understood. although, fresh years have visible a number of the parts of crystal-field results mature to the purpose that they need to be summarized and taken to the lively observe of a bigger viewers. additionally, a couple of interesting advancements have occured which deserve consciousness. This publication comprises thirteen invited and forty five contributed papers pres­ ented on the second overseas convention on crystal-field results in metals and alloys held at ZUrich, Switzerland, September 1-4, 1976. Emphasis was once put on the subsequent particular different types of curiosity: spin waves and excitons, delicate modes and important results, magnetic homes, actual homes encouraged through crystal­ box results, actinides and valency. as the convention used to be really small, approximately a hundred and twenty individuals, and as the subject was once fairly slim, fresh paintings within the box can be taken care of thor­ oughly and the current country of data assessed comprehensively.

5 K PrSn3 is a type A antiferromagnet (1-4). The particular interest, however, arises from the superconducting properties for low Pr concentration (5). Moreover, resistivity measurements (6-7) suggest that these compounds are Kondo systems. For a Quantitative understanding of all these effects information on the crystal-field levels is indispensible. 31 32 A. FURRER, A. MURASIK, AND Z. KLETOWSKI In the present work we report on the crystalline electric field levels of PrSn3 determined by neutron spectroscopy.

The overall agreement with the observed energy spectra is rather good. 2 K data. These excited-state spin-wave intensities result directly from the large transition matrix elements and the popUlation factor.

Stevens and pytte (10) have suggested a distortion pattern to explain the flopside spin structure. They suppose that the phosphorus ions are alternately displaced along the +x and -x directions, so that half the Ho ions are in compressed octahedra of their neighbours and half in extended octahedra. In this model the two sublattices are not equivalent. A similar distortion has recently been found in U0 2 (11). 30 A. M. LEVY, AND E. KALDIS Neutron diffraction experiments on single crystals would be highly desirable to further elucidate these questions as well as to check the temperature dependence of the order parameters and the nature of the phase transition.
