    Dielectric Constant and Hysteresis Loop Remanent Polarization from 100 Hz to 2 MHz for Thin Ferroelectric Films

    A modification of the standard Sawyer-Tower circuit method of displaying ferroelectric hysteresis allowed the technique to be extended to sinusoidal switching frequencies of 2 MHz. Using this method, probe sta...

    In Situ Characterization of the Pulsed Laser Deposition of Magnetic Thin Films

    Pulsed Laser Deposition (PLD) has been proven as an effective means of depositing films from refractory targets. In our earlier work, either Nd/YAG or excimer lasers, interacting directly with target surfaces,...

    Lead Zirconate-Titanate Thin Films Prepared by the Laser Ablation Technique

    Lead zirconate-titanate (PZT) thin films were prepared by the laser ablation technique. The PZT (Zr/Ti=53/47) target was irradiated using a focused q-switched Nd:YAG laser (15 ns, 100 mJ at 1.064 μm). The as-d...
