Remanence Plots as a Probe of Spin Disorder in Magnetic Nanoparticles

the significance of conjunction as a cohesive device in teaching writing

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...

Magnetic remanence of Josephson junction arrays

In this work we study the magnetic remanence exhibited by Josephson junction arrays in response to an excitation with an AC magnetic field. The effect, predicted by numerical simulations to occur in a range of temperatures, is clearly seen in our tridimensional disordered arrays. We also discuss the influence of the critical current distribution on the temperature interval within which the arra...

Synthesis of Magnetic Remanence Correlation , Leg 155

Conventional magnetic stratigraphy was not possible due to the young age (<780 ka) of the recovered sediments. Taking advantage of the exceptionally high sedimentation rates, however, we were able to successfully adopt several other less-utilized magnetostratigraphic techniques. Foremost among these was the identification of short periods of anomalous geomagnetic polarity (i.e., events and excu...

Magnetic susceptibility measurements as a probe of spin transfer driven magnetization dynamics

Remanence effects in the electrical resistivity of spin glasses

We have measured the low temperature electrical resistivity of Ag : Mn mesoscopic spin glasses prepared by ion implantation with a concentration of 700 ppm. As expected, we observe a clear maximum in the resistivity ρ(T ) at a temperature in good agreement with theoretical predictions. Moreover, we observe remanence effects at very weak magnetic fields for the resistivity below the freezing tem...
