We then will discuss several novel materials and interface-induced effects occurring in magnetic heterostruct ures: The growth of altermagnetic thin films and their integration in magn etic tunnel junctions with barriers such as RuO<sub>2</sub> are at present intensively investigated due to their potentially spin-split band structu re and related spin currents. X-ray analysis reveals a high crystalline qu ality of the films with or without twinning depending on the choice of the substrate. When integrated with an MgO tunnel barrier and a ferromagnetic counter-electrode\, signatures of a tunneling magnetoresistance strongly depend on the bias voltage and are not yet fully understood. When integrat ed with ferromagnets (Ni<sub>80</sub>Fe<sub>20</sub>) or heavy metals (Pt) \, an analysis based on the 2ω method shows the presence of torques in ac cordance with a spin current at the interface. When replacing the altermag net by a ferromagnet\, the heavy metal can show a proximity-induced ferrom agnetism at the interface\, which substantially influences the results of well-known phenomena such as the spin Seebeck\, anomalous Nernst\, or anom alous Hall effects. Examples will be discussed using metallic as well as i nsulating ferro- or ferrimagnets and recipes for disentangling the many ef fects will be given.\n\nAgenda: \n6:30 - 7:00 Socializing and Networking a t Quadrant\n6:55 Zoom session will be online with Waiting Room\n7:00 - 7:4 5 Lecture begins\, online and in person\n7:45 - 8:00 Questions and Answers \n\n1120 Ringwood Ct\, San Jose\, California\, United States\, 95131\, Vir tual: https://events.vtools.ieee.org/m/480903 LOCATION:1120 Ringwood Ct\, San Jose\, California\, United States\, 95131\, Virtual: https://events.vtools.ieee.org/m/480903 ORGANIZER:t.gardner@computer.org SEQUENCE:67 SUMMARY:New Materials and Interface Effects In Charge and Spin Transport In Magnetic Heterostructures URL;VALUE=URI:https://events.vtools.ieee.org/m/480903 X-ALT-DESC:Description: <br /><p>A presentation by Professor Guenter Reiss\ , Ph.D.\, Bielefeld University\, Bielefeld Germany\, on magnetic heterostr uctures which are key devices for spin electronics. &nbsp\;</p>\n<p>An int roduction will present examples of basic effects and their applications.
