Temperature Measurements Using Small Quantities of Cerium Magnesium Nitrate

Abstract

Impact of the metal cathode and CsF buffer layer on the performance of organic light-emitting devices

Heat flow in superfluid 3He

“…cavity. Its temperature was determined as described by Abel et al 3 using a standard 17-Hz mutual inductance bridge with the modification that the compensating secondary was wound in two sections, one above the measuring secondary and the other below it. The measuring field on the main CMN from the primary coil was kept at 0.385 G rms : this was small enough to avoid any measurable heating of the CMN down to the lowest temperature of interest for this experiment, about 2 mK.…”

The role of imperfections on magnetic and thermodynamic properties of cerium magnesium nitrate in the low-temperature magnetic phase transition region

“…The sample was inside a glass envelope kept at 1.2 K on which the primary and secondary coils, parts of a Hartshorn bridge (as described by Maxwell16), were wound. The coils were similar to those described by Abel et al 17 with a primary 17.8 cm long with 4000 turns of wire and two secondary coils with 10,000 turns of wire each astatically wound and connected in opposition. Each secondary coil was 5.08 cm long with its center 5.08 cm from the end of the primary.…”

Magnetic Thermometry

“…1 (b).3 This reduces the capacitive problem appreciably, but does not eliminate it. 4 Furthermore the linearitv of the , . bridge is limited by the input impedance of the amplifier.…”
