So as I understand it, GMR effect is basically a branch of the broader field that is Spintronics, but the STT allows for further advancement of the field. Just another thing. In this article http://www.sciencedaily.com/releases/2010/12/101216142511.htm In the last section, it is mentioned...

Hey all, First of all, I'm not sure if this is in the right forum-- if not, sorry about that . I am doing a presentation on Spintronics as part of my 2nd year Physics coursework at University. In researching, I see that there is a great link between the Giant Magnetoresistance Effect...

BUMP Presentation is 5 weeks from now, so far I have set my mind on Spintronics--- but any further ideas would be great!

Hey guys. I am required to do a presentation in physics (obviously) for about 15 mins or so. They haven't specified any parameters so what the topic can be is flexible. I wanted to something along the lines of physics that could be used in some emerging technology e.g. spintronics. Any...

I am aware of the concepts of conservative and nonconservative forces, but my tutor said that there is a special name for this case. I remember him distinctly mentioning something along the lines of "dissipative".

What kind of a vector force field is this? Just a general physics question: I was given a force field vector a(x^2, 2xy, 0) where 'a' is a constant. When I performed a line integral from (0,0,0) to (1,0,0) to (1,1,0), I get 4a/3. Doing it from (0,0,0) to (0,1,0) to (1,1,0) gives a/3...

Homework Statement A capacitor consists of two plane parallel plates, separated by a distance d. The space in between is filled with a uniform charge density J. Find the electric field at a point x away from the positive plate when a potential difference V is applied. Homework Equations...

Ah I see now -- thanks for your help!

Homework Statement A disc has radius a and rotates with angular frequency w. Magnetic flux density is B. Such a disc of mass 10^4 kg and radius 3m is rotating freely at 3000 revs/min in a field of 0.5T. A load of 10^-3 ohms is connected suddenly between the rim and the axis of the disc...

Never mind -- I think I have the answer now.

Just bumping this -- any help at all would be great.

Homework Statement It is required to put a satellite into an orbit with apogee of 5R/2, where R is the radius of the planet. The satellite is to be launched from the surface with a speed Vo at 30degrees to the local vertical. If M is the mass of the planet, show that (Vo)^2 = 5GM/4R. Assume...

Homework Statement Two particles of mass m are connected by a light inextensible string of length l. One of the particles moves on a smooth horizontal table in which there is a small hole. The string passes through the hole so that the second particle hangs vertically below the hole. Use the...

Homework Statement A small sphere is dropped from rest at a height 'h' above a plane inclined at an angle θ to the horizontal ( < 90degrees ). Given that the sphere loses no energy on impact, show that the distance down the plane between this impact and the next is 8hSinθ. Homework...

Homework Statement A particle of mass m is constrained to slide on the inside of a vertical smooth semi- circular ring of radius r. The position of the particle is described by a polar coordinate system whose origin is at the centre of the circle with axes along the orthogonal unit vectors...
