Patent number: 8345516Abstract: The invention relates to a magneto-optical switching device for switching magnetization in a medium, comprising a magnetizable medium. According to the invention, a radiation system suited for imparting angular momentum to the magnetic spin system of said magnetizable medium, so as to selectively orient the magnetization of said medium. In addition, the invention relates to a method of switching a magnetizable medium, comprising providing a magnetizable medium; providing a radiation beam of a selectively chosen angular momentum; and targeting said radiation beam to said medium so as to transfer said angular momentum to a magnetic spin system of said magnetizable medium. Accordingly, spin states in magnetic materials can be manipulated using radiation of a suitable angular momentum. An effective magnetic field is generated for orienting the magnetization of the domains and can simultaneously be used to locally heat the material.Type: GrantFiled: November 7, 2011Date of Patent: January 1, 2013Assignee: Stichting Katholieke UniversiteitInventors: Theodorus Henricus Maria Rasing, Andrei Ivanovitch Kiriliouk, Alexey Voldermarovitsj Kimel, Claudiu Daniel Stanciu, Fredrik Hansteen, Akiyoshi Itoh, Arata Tsukamoto

Patent number: 8077546Abstract: A method for monitoring a multi-layered system below a surface comprising a slow layer and a fast layer; the method comprising: transmitting one or more seismic waves from one or more seismic sources through the multi-layered system; receiving signals emanating from the multi-layered system in response to the one or more seismic waves with one or more receivers located a distance from the one or more seismic sources; identifying one or more critically refracted compressional (CRC) waves amongst the signals; and inferring information about a change in the slow layer based on the one or more CRC waves; wherein the CRC wave is a refracted wave which has traveled along an interface between the fast layer and an adjacent layer.Type: GrantFiled: May 4, 2009Date of Patent: December 13, 2011Assignee: Shell Oil CompanyInventors: Fredrik Hansteen, Peter Berkeley Wills
