12. 1216 May 2012 FeCo - Hiperco Purchased from Ed Fagan –Hiperco 50 (A) Cut to size on site Annealed at IFW in Dresden, Germany –871 deg C, 2h in vacuum

13. 1316 May 2012 FeCo – Hiperco 50A

14. 1416 May 2012 FeCo – Hiperco 50A

15. 1516 May 2012 FeCo – Comparison GO Steel

16. 1616 May 2012 Fe Co Results about 0.1T short reason is unknown –wrong material –bad batch –not enough material –wrong annealing Vacuumschmelze GmbH & Co. KG –Hanau, Germany

17. 1716 May 2012 Vacoflux 48

18. 1816 May 2012 6.5% Si steel –confirmed values from datasheet –almost isotropic –good match of hysteresis loop –losses? FeCo –discrepancy between datasheet and measurement –Vacuumschmelze Summary
