Heat capacity of gadolinium near the Curie point
… has been observed close to the ferromagnetic Curie point at about 180 C. An ""ac"" or temperature modulation method allowed the use of very small single crystal samples. The heat capacity peak for our best sample is rounded in a range of lO at the Curie point (Tc ). Outside this region, good …

Resistivity anomalies for ferromagnetic metals at Curie points
… anomalies of ferromagnetic metals at the Curie point using the itinerant model. The nature of these resistivity anomalies is related to phase transitions of second kind. Current theory describing these anomalies is based on the localized model of the magnetic electrons in ferromagnetic …

The Development and Evaluation of Novel Techniques for the Study of Polymerisation and Degradation Reactions
… the latter being coupled to in-line filament and Curie point pyrolysis techniques. A further technique is incorporated which enables rheological studies of residual polymer in the melt state to be carried out during degradation processes. The potential applicability of the above equipment to the …

Magnetic domain formation in La1-xSrxMnO3 nanowires studied with resonant soft x-ray scattering
… the magnetization at temperatures far below the Curie point of the bulk material. Around this temperature, coexisting phase separated domains were observed with transport measurements. To understand these observations, resonant soft x-ray scattering studies were performed on Mn L-absorption-edge …

Fabrication And Damping Behavior Of Particulate BaTiO3 Ceramic Reinforced Copper Matrix Composites
… was high from room temperature up to the Curie point of barium titanate, after which there was a slight drop in damping values probably due to a loss in ferroelectric properties. The small drop in damping values recorded in excess of the Curie temperature is an indication that …

Resonance Tracking and Vibration Stabilisation of Ultrasonic Surgical Instruments
… heat generated in the joint area and the low Curie point of PMN-PT. The needle actuating device can increase the visibility of standard medical needles in colour Doppler imaging. <br/>

Magnetic and electric properties of bismuth ferrite lead titanate ceramics
… induced upon cooling through the ferroelectric Curie point from cubic, to the distorted tetragonal perovskite phase (ܿ/ܽ = 1.17). This drives a further partial transformation to the (~4 %) lower volume rhombohedral phase as a relief mechanism. Increasing the sinter temperature and fast cooling …

Reactor protection system design alternatives for sodium fast reactors
… the reactor protection system. Of these, the Curie point latch marginally reduces the conditional cladding damage probability for metal cores because of their rapid inherent feedback effects, but is more effective for the more sluggish oxide cores given reasonably long pump coastdown times. …

Advanced propulsion for microsatellites
… were estimated to reach 900°C, exceeding the Curie point of iron. As a consequence of the change in the magnetic field profile and the resultant leakage of electrons, the observed ionization fraction and, therefore, the utilization efficiency were lower than expected. Despite the low …
