Magnetic Thermometry

Abstract: Application of magnetization measurements in iron to high temperature thermometry . The paper ?escribes a highly stable ac mutual inductance bridge suitable for low temperature use. The applica-tIon of the bndge to magnetic thermometry below 3 K is discussed. *

“…This implies a somewhat different theory, or at least a different order In which the perturbations are applied. In particular, the spin-orbit coupling is 2 very large for these ions and the F ground state is split into doublets with first excited doublet lying 38 The brief discussion of these three salts suggests that their behavior approximates Curie's Law fairly closely and in particular, that the magni tudes of the correction terms, a and 6, are sufficiently small to be tractable. A sound theoretical calculation which evaluates 6 exists for ths susceptibility of CMA.…”

“…The lower thermal expansions and hence greater Ml stability of the coils which would result make the use of a He^ bath attractive, although the liquid bath proved to be adequate for' the present work. Anderson (38) describes a method for locating the reference Ml near the measuring coils in such a manner that it is un affected by the salt moment.…”

“…Para resolver este problema foi projetado um "probe", que será descrito a seguir, com uma eficiente blindagem magnética. As espiras do enrolamento primário e secundário, mais próximas entre si, foram submetidas a um mesmo potencial [42] . Ou seja, a camada, de espiras, mais externa da bobina secundária e a mais interna da primária estão em um potencial terra.…”

“…Estudos de susceptibilidade magnética DC realizados em polianilinas e derivados [112][113][114][115][116][117][118] mostraram que a susceptibilidade pode ser descrita a partir de duas contribuições: uma independente da temperatura, proveniente do paramagnetismo de Pauli e do diamagnetismo da cadeia polimérica; e outra dependente da temperatura devido ao Assim, como no caso do poliparafenileno (Capítulo 5), é interessante calcular a contribuição diamagnética da cadeia polimérica, utilizando a regra de adição de Pascal, exemplificada na Eq. (42). A fim de possibilitar comparações com resultados apresentados na literatura [112] , o cálculo foi realizado referindo-se à susceptibilidade molar para uma molécula reduzida contendo 4 anéis benzenos.…”
