Spring Seminar Series

Join us as Amlan Biswas of Florida University gives a talk entitled:

Dielectrophoretic Behavior in Electronically Phase Separated Manganite Thin Films

Competing ferromagnetic metallic (FMM) and insulating phases in the manganite (La1-yPry)1-xCaxMnO3 (LPCMO) leads to a phase separated state in which micrometer scale FMM regions behave in a fluid-like manner over a narrow temperature range (Fig. 1). I will discuss our experimental results which show that an electric field can realign the fluid-like FMM phases embedded in an insulating matrix resulting in anisotropic in-plane resistance in microstructures of LPCMO thin films. Time and voltage dependent resistance measurements show that the dynamic percolation of the FMM regions leads to an insulator to metal transition due to electric field induced realignment of the FMM regions which is analogous to the dielectrophoresis of metallic particles suspended in fluid media. In-plane strain anisotropy plays an important role in determining the speed of dynamic percolation of the FMM regions by modifying the local electric fields in the phase separated state. I will also show that small magnetic fields (~100 Oe) can significantly modify the dielectrophoretic behavior. These observations suggest an unconventional form of magnetoelectric coupling.

*CNS 204* @ 12:10 p.m.

Physics Café – Thursday February 6 2014 7:00 PM – 8:30 PM – Emerson Suites - Free and open to the public.

Matthew Price of the Ithaca College Department of Physics & Astronomy talks about:

The Particle Zoo: The Newest Exhibit, the Higgs Boson.

Recent discoveries at the Large Hadron Collider have helped to find the elusive Higgs Boson have led to the 2013 Nobel Prize in Physics being awarded to Francois Englert and Peter Higgs. Professor Matthew Price will be speaking about the Standard Model of Particle Physics and the newest addition to the particle zoo. We will explore the past, present and future of particle physics now that the most elusive particle has been confirmed.

Doctor Price is an Assistant Professor in the Ithaca College Department of Physics and has worked in Particle Physics, Astrophysics, Solid State Physics, and Physics Education. He has worked on understanding the structure of the proton as well as understanding how students think about physics.
