Thin film samples for investigating magneto-transport
mechanism are described. The samples are observed in two methods. The first
method consists of annealing the samples at different temperatures. The
samples are place in a magnetic field and current is passed through the
samples. The GMR, Halls voltage and temperature are recorded at
different times of regular intervals for analysis.
A LabVIEW program is
developed for collecting data from the magneto-transport device. A plot is
constructed from the collected data and compared with other research
findings and analysis. Next, the IV characteristics of the samples are also
observed. A LabVIEW program is designed to increase the current and
measure the voltage and temperature at regular intervals. The importances
of the experiment are given.
